Kanye West decided to follow 1 random follower like @conanobrien did. When Conan followed this lucky random follower she loved it and her followers grew to 30,000.
Kanye West just recently did the same thing by tweeting: "@ste_101holy shit bro thx for following - You are the chosen one dun dun dun dun" (which I have to point out...Kanye didn't put a space between the user's @ name and "holy".....but Kanye will learn the more he tweets!:P ).
The follower "Steven Holmes" from England tweeted "This has been completely surreal and I really have no desire for this attention i'm just a normal person." and then moments later "I won't be speaking to anybody else, surprisingly not everyone wants to be famous. That's all I'm saying - peace out x." @ste_101 then removed his picture from his twitter account it appears he will no longer be using that account.
I think many other followers of Kanye would love the chance to be followed like that.
